Evolution of Intramedullary Screw

Intramedullary screws are type of implant designed to sit within the bone being fixated. Benefits of intramedullary fixation include little to no hardware prominence, ease of implantation, and the allowance of micromotion about a fracture site to provide stronger bony healing.

Intramedullary screws can be fully-threaded, partially-threaded or variably-threaded, depending on fixation strategy utilized. They are often cannulated, which allows for insertion over a guidewire. Where strength is of a concern, solid implants can also be used, which provide a much stiffer ultimate fixation construct.
